    AIOFM Fourier Transform Infrared Spectroscopy Team Helps Develop Six Standards for Chinese Herbal Medicine Grades

    Six group standards for the commercial specifications and grades of Chinese herbal medicines, issued under the Anhui Provincial Association of Chinese Materia Medica, have been released. The team led by researcher Li Xiangxian at the Anhui Institute of Optics and Fine Mechanics (AIOFM) was among the principal drafting units, covering Peucedanum root, Clinopodium herb, Atractylodes macrocephala root, Moutan bark, red peony root, and white peony root. The standards classify grades primarily by morphological characteristics and active ingredient content. The team applied the advantages of Fourier transform infrared spectroscopy - rapid, nondestructive, and multicomponent detection - to the quality evaluation of Chinese herbal medicines, and demonstrated mid-infrared and portable near-infrared FTIR analyzers.

    Hefei Institutes Develop Dual-Differential Sphere-Tube Coupled Photoacoustic-Scattering System for Simultaneous Aerosol Optical Measurements

    A team led by Researcher Fang Yonghua at the Hefei Institutes of Physical Science has developed a dual-differential sphere-tube coupled photoacoustic-scattering system that simultaneously obtains aerosol absorption and scattering coefficients at 450 nm and 532 nm within a single sampling path and shared measurement volume. The results were published in Photoacoustics. Two laser beams are modulated at 2572 Hz and 169 Hz and demodulated by frequency using an FPGA-based digital lock-in amplifier. With a 1 s integration time, detection limits for the 532 nm absorption and scattering channels are 1.2 Mm⁻¹ and 1.32 Mm⁻¹, respectively.

    AIOFM Develops Digital Hydrogel Fluorescence-Enhanced Microsphere System for Amplification-Free Relative Quantification of CRISPR Nucleic Acids

    The Optoelectronics Center of the Anhui Institute of Optics and Fine Mechanics published a paper in Analytical Chemistry describing CrisprDEM, a digital hydrogel fluorescence-enhanced microsphere detection system based on CRISPR/Cas12a that enables amplification-free relative quantification of nucleic acids. The system uses hydrogel microspheres to enrich fluorescent reporter molecules, boosting the fluorescence signal by a factor of about 1,000. A microfluidic chip then spreads the microspheres into a monolayer for imaging, and a K-means algorithm distinguishes positive from negative microspheres, with the proportion of positive microspheres used for quantification.
